I'm inclined to agree, but I'm not dead certain what "without anti-aliasing" means in this specific context. Can you clarify, preferably with an example or two? A link is okay.

I can't provide a visual aid at the moment (I will later today) but let's say I have a 5x5 pixel image. I want to increase the size to 10x10 (and thereby scale it up 2x) but without any anti-aliasing occurring between pixels.

Why not use vector based graphics which would allow infinite resizing without loss of quality?

There are free programs like Inkscape or payed programs like Adobe Illustrator. With these you will be able to make the graphic to a specific height/width then rasterize (the process of turning mathematically defined lines to pixels) the final to a jpeg or whatever file form you need.
